I decided this morning to switch to the beta of blogger to see how much is improved. The layout can be configured much easier than before and there are a few new options. Unfortunately the atom feed for the blog has changed, so if you used it before, you have to change your akregator.
For just publishing a post, there's not much difference. Uploading photos I now see them in the confirmation window, I can add labels to blogs but nothing really fancy. The major facelift you might notice is the Blog archive.
